JOSEPH F. VOG-EL, OF NEW YORK, N. Y.

BRACKET.

To all whom it M ay concern Be it known that l, Josnrn Vocnn, citizen ofthe United States of America, and a resident of liew York, county ofBronx, and State of New York, have invented certain new and usefulimprovements in Brackets, of which the following is a specification.

My invention relates to brackets such as are employed for clampingarticles together, or for clamping various articles to a suitablesupport, and comprises an improved construction of bracket, wherebyrigidity is obtained in a bracket composed of relatively light members,and whereby parallelism between the sides of the bracket is secured.

My improved bracket is particularly intended for use as a part of thewrist supporting and guiding attachment for pianos and the like,illustrated and described in my application for Letters Patent filedDecember 10, 1913, Serial l lo. 805,778; but said bracket is alsoadapted for various other uses.

My invention consists in the novel con struction and arrangement of theparts of the brac :et, as hereinafter described, and particularlypointed out in. the appended claims.

The object of my invention is to provide a light, simple and inexpensivebracket, which, may be made light and yet shall be very rigid and mayhave a wide span.

I will now proceed to describe my invention with reference to theaccompanying drawings, and will then point out the novel features inclaims.

In the drawings: Figure 1 shows a side elevation of a bracket embodyingmy invention, said bracket being shown as provided also with a slidemember adapted to move along the arms of the bracket which slide member,in my wrist support above referred to, is employed for carrying thewrist guide; though said slide member is also adapted for other uses;and Fig. 2 shows, in section, two such brackets, in connection with thesaid wrist guide, the section being taken on the line :cm of Fig. 1.

Referring first to Fig. 1, numeral 1 designates the bracket, ofapproximately U-form, having a spread or span adapting it to be securedto a piano or other instrument, or to any other suitable support. Theupper arm of the bracket is provided with a Specification of LettersPatent.

Patented Got. 6, 1914.

Divided and this application filed March cushion 2, of rubber, felt orother suitable soft and yielding material, such as will permit clampingof the bracket to the piano or other suitable support, without injury tothe finished or varnished surface of such support. In practice thiscushion 2 is commonly attached to a block 3 of wood or other suitablematerial, suitably secured to the upper arm of the bracket. It is notordinarily necessary to provide for adjustment of this block 3, in andout on the bracket. The lower arm of the bracket is provided withsuitable clamping means such as clamping screws 4, adapted to engage theunder side of the piano or other support. I have illustrated'theprovision of two such clamping screws l on the bracket, but do not limitmyself to any particular number of clamping screws, or to the use ofclamping screws as distinguished from other equivalent clamping means.To insure rigidity of each bracket 1, notwithstanding the lightness ofthe construction of the bracket, and to insure substantial parallelismof the two arms of each bracket (such parallelism being desirable since,as hereinafter described, a sliding member is or may be mounted to moveback and forth on the two arms of the bracket) I connect the two arms ofthe bracket by a tie rod 5 or equivalent connection, such tie rod 5being screw threaded into the two arms of the bracket, or otherwiseconnected in any other suitable manner. 7 designates a slide memberadapted to move along the two arms of the bracket. It will be obviousthat, in order that the slide member may so move, substantialparallelism of the two arms of the bracket is necessary; this is onereason for the provision of the tie rod 5.

In Fig. 2 I have shown two of these brackets 1 in connection with awrist-supporting rod 6, supported from the slides 7 of the two brackets.For the adjustment of this wrist guide 6 in a direction at right anglesto the direction of motion of the slide 7, I have provided, on the twoslides 7, arms 8 to which arms the wrist guide 6 is directly connected,such arms 8 having slide bearings 9 on the slide rods 7. Suitableclamping screws 10 or other equivalent clamping means are provided forsecuring the arms 8 in any position to which they may be adjusted on theslides 7 No similar fastening means are ordinarily required for theslide bearings 7 of the slide 7, since the natural cramping of the saidbearings on the arms of the bracket 1 ordinarily suffices to hold theslide rods 7 in any position to which they may be adjusted; but theslide rods 7 may nevertheless be moved in and out on the arms of thebrackets 1 very readily, when this is desired.

I do not in this specification claim the complete wrist supportillustrated in Fig. 2, as such wrist support is claimed in my priorapplication Sr. N o. 805,7 78, above mentioned, of which the presentapplication is a division; and in this present application I haveillustrated the complete wrist guide as showing one application of myimproved bracket, and as showing one use of the bracket in whichparallelism of the sides thereof is desirable. It will be obvious thatmy bracket, with or without the slide member 7, is adaptable for variousOtllQlilSQS, and I do not limit it to use as a part of the wrist guideillustrated and described.

What I claim is 1. An attaching bracket such as described, comprising aU-shaped member, a tie member connecting the arms of the U at pointsintermediate the ends and base of the U, said arms of the U beingparallel between said base of the U and said tie member, said U shapedmember provided, between the said tie member and the ends of its arms,with means for securing said bracket to a suitable support, and a slidemember having sliding bearings on the arms of said bracket and movablein and out along said arms.

2. An attaching bracket such as described, comprising a ll-shapedmember, a tie member connecting the arms of the U at points intermediatethe ends and base of the U, said arms of the U being parallel betweensaid base of the U and said tie member, said U-shaped member provided,between the said tie member and the ends of its arms, with means forsecuring said bracket to a suitable support, a slide member havingsliding bearings on the arms of said bracket and movable in and outalong said arms, and an arm having a slide bearing on said slide memberand movable therealong.

In testimony whereof I have signed this specification in the presence oftwo subscril' ing witnesses.
